 See nonMaxSupr for more information.  Has the same effect as nonMaxSupr
 except it operates on a list of position/values pairs.  Running time is
 n^2 in the number of such pairs.  For comparison running time of
 nonMaxSupr is ord( sum( size(I,d)*radii(d) ).

 This function has an additional parameter - flag. If flag==1, then all
 locations that are not strictly the biggest in their window are
 suppressed (ie, keeps max only if it is UNIQUE).  This can be useful for
 large flat regions -- nonMaxSupr(ones(30),3) does no suppression since
 all values are equal in each window, but nonMaxSuprList(ones(30),3) w
 flag==1 suppresses all locations. If flag==2 ties are broken randomly (in
 fact this allows for slightly faster execution).

 USAGE
  [subs,vals,keep] = nonMaxSuprList( subs, vals, radii, ...
    [thresh], [maxn], [flag] )

 INPUTS
  subs       - subscripts of point locations (m x d)
  vals       - values at point locations (m x 1)
  radii      - suppression window dimensions
  thresh     - [] minimum value below which not to look for (or [])
  maxn       - [] return at most maxn of the largest vals
  flag       - [] suppress equal vals (see above)

 OUTPUTS
  subs       - subscripts of non-suppressed point locations (n x d)
  vals       - values at non-suppressed point locations (n x 1)
  keep       - indicies of kept locations from subs (n x 1)
